Firmware Upgrading
1) Make sure the DC switch is off and the AC is disconnected with grid. User can update the inverter system through the U-disk.
Please contact SolaX service to get the latest firmware. Then add a new folder named “Update” in the root directory on your U-disk, and two more sub-folders named “ARM” and “DSP” under “Update”. Please copy the firmware files into ARM and DSP respectively. It will be like: “UpdateARM618.00207.00_XX_XXXXX_XXXX_XXX_ARM_Vx.xx_xxxxxxxx.usb”; “UpdateDSP618.00381.00_XX_XXXXX_XXXX_XXX_DSP_Vx.xx_xxxxxxxx.usb” 2) Press and hold the “v” key for 5 seconds to enter Off Mode. Then insert the U-disk into the “DONGLE” port.
